    @AG- I have used your recommendations along the way. These are the changes I am using, based on your advice: 1. I am using your voltage divider circuit, rather than the original 2. I am using a 10nF capacitor in place of the 470nF 3. I used a 3.3uF capacitor instead of the 330nF originally...

    I bought some 1uf capacitors. They only had 50volt ones, so I bought those. I didn’t realize that their cap size is bigger. Aside from the size inconvenience, there is no reason they wouldn’t worth in this circuit right?

    Thanks Bertus. Yes, I remember that. But the original schematic had a 470nF capacitor- whihc, as AG said, was way too big. So. given that it started with a 470nF, just wondering if it would work with a 15nF even though it may take a little more time that a 10nF. Far better than 470-nF I would...

    Thanks Bertus. Here is a pic of my new build this far. The voltage divider has been built and I just fastened the socket for the op amp. Nothing else has been done yet beyond that. Question> The circuit calls for a 10nF capacitor just after the input (this is a change AG recommended- the...

    Hi Bertus: Yes I am. I have both kinds, but on this build, I am using the Turned Pin type. I just built the new voltage divider part of ther circuit. Before the 1M, my volt reading is 4.7. After the 1M, the volt reading is 4.2. I am using a new battery now. I think those readings are good- right?

    I replaced the 1m resistor. When I tested the circuit, it worked for about 5 seconds. and then went dead. I may do a rebuild. Something is quirky. Maybe a faulty component.

    So, this is interesting. One end of the 1M resistor (the end that connects to the two 100K restores to make the voltage divider, measure at 3.8V - whihc is normal. BUT..the other end of the 1M resistor- the end that goes to Pin3, measures 0 volts coming out- which is a problem. Does this mean...

    Thanks. I wil start by checking the switches orientation. Bertus, thanks for the link. @AG- I’m with you and as I said, my pin readings have been perfect, which means I am wiring the pins correctly. How stupid of me. I think I have the switch 90 degrees off. I took a quick look. I am building...

    Hi guys...I hate to say it, but I need your help again . As you know, I have been building this circuit rather successfully and have recently installed the stomp switch in prototype mode, successfully. So I moved on to regular build on a PCB. This happened twice now: I get the circuit built...

    Thank you VB. I will order the Amazon ones for two reasons 1. Digi keys looks great but last time I tried ordering something, I was facing a $20 surcharge on a $12 order. I should try it again though 2 I own Amazon stock so always try to support it

    Will these work? Not sure if they have three lugs. https://www.amazon.ca/dp/B01N8VV78D/ref=cm_sw_em_r_mt_dp_N2Y1YT166WB8CQP5KQKP if not, does anyone know where on Amazon I can find them? thanks

    The Final Act

    So, I have managed to build an overdrive pedal, complete with a real stomp switch and a LED that lights when the effect is active. The only thing left to figure out, is how to include an A/C plug that, when plugged into an adapter, cuts off the 9 volt battery power, and runs on the AC adapter...

    Need equivalent to this part. In stock in USA supplier

    You may want to find the schematic if you can.

    Thank you. I may change my tip. Presently, I am using one with a very sharp point, like a sharp pencil

    I'm not sure I can pull that off using the through hole soldering method. That's a lot of soldering and each connection must be perfect. Hmmm

    Stomped Out

    Thanks Harald. Because I have been building these circuits successfully, I got over confident and did not test this before wiring the switch. I am doing a rebuild and a test. Yes, the green parts are good.

    We’ll see. I don’t give up easy and I also don’t feed ca food to a Lion. Lol. Thanks for the vote of confidence. I agree that when you breaks things down, it gets understandable
